A model of the theory of endosymbiosis is shown here. It is an explanation for the presence of chloroplasts and mitochondria as organelles that might have had an origin as free-living prokaryotic cells at one time. Evaluate each statement below and select the ones that accurately describe how evolution and endosymbiosis gave rise to life on Earth as we know it today. A) Endosymbiosis provided a benefit for the engulfed prokaryote and the host cell that engulfed them.

B) The energy provided by the photosynthetic or aerobic bacteria allowed for greater success of the host cell.

C)Only cells that were able to perform endosymbiosis and become eukaryotic were provided a mechanism to survive.

D) Endosymbiosis was a directed process as eukaryotic cells needed additional organelles for energy and metabolism.

E) Cells that engulfed photosynthetic or aerobic bacteria had a survival advantage and we able to reproduce more successfully, leading to their evolution and proliferation.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

because the light is a great source of energy for the plants to survive. (i hope this )
